George R. White attempted to make the first successful bird-like flight in history. White is in his foot-propelled, wing-flapping, motorless ornithopter. It crashed on the test flight, but it was later improved. Photographed September 21, 1927.

I would like to see a strap-on backpack ornithopter developed, so that people could fly around like Hawkman.
